END-LASTING WIPER.

Specification of Letters Patent.

Application filed October 19, 1910.

Patented ov. 25V, 1913. Serial No. 587,972.

To all whom t may concern:

'Be it known that I, WILLIAM A. S'rUBs, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain Improvements in End-Lasting Wipers, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. Y

This invention relates to machines for use in making shoes and particularly to end lasting apparatus. This apparatus asembodied in the bed type of lasting machines usually comprises end embracing wipers for the heel and the toe which present a substantially continuous wiping edge and are actuated to advance longitudinally of the shoe and close inwardly from opposite sides to wipe the upper over the edge of the shoe bottom into position to be fastened.

The invention is here represented for exemplication as embodied in wipers of this type which are adapted for lasting the heel portion of a shoe.

In lasting shoes over many styles of lasts l in use at the present time, diliicultyhas been experienced in wiping the upper into proper 4 lasted position at the inner side of the shoe at the front of the heel and inthe shank. This diiiculty arises from tliefactk that the lasts referred to are cut under deeply at the inner 'side'of the shank and the upper must be wiped far inwardly on this side in order to work it into position to be secured to the innersole. this purpose it is important forthe wiper proper y For Y operating on the inner side of the shoe to reach far forwardly. It is,` however, not.

desirable that the wiper which acts `on the outer side of the shoe shall reach so far forwardly for if it did so its closingmovement would be obstructed by the rib on the;

welt shoe and it would cover the tacking line on a McKay shoe.

In accordance with this invention last-v ing mechanism is adapted for positioning movement to present for action at one side of the shoe a wiping edge which is substantially longer, or extends fart-her forwardly toward or along the shank, than the wiping edge presented for action at the other side of the shoe. In the illustrated embodiment of the invention the wipers are provided continuation of the wiper when the exposition and 1s arranged to be turned backwardly into an inoperative relation when its use vis not desired.

In the preferred embodimentof the invention a wiper extension is provided on the front end of each of the heel wipers, being pivotally connected thereto and having a construction cooperating with the construction of the wiper whereby it is rigidly held 1n operative position and is also retained in inoperative position when it has been turned into that relation to the main wiper.

The several features of the invention will now be more fully explained in connection wit` the accompanying drawing and will then e pointed out in the claims.

Figure l is a plan-view of a heel lasting mechanismembodying this invention; Fig. 2 is a perspective view of the under side of the wiper showing the extension in operative position and disclosing'the format-ion of the wiper and its extension by which the latter is held rigidly against working strains while in its operating position.

The heel lasting mechanism represented in the drawings is of a commercial type and requires no detailed description.

The wipers 2 are supported for sliding movement forwardly and inwardly, which movement is imparted to them by link 4 connected by a crss-head 5 to an operating rod 6, which is moved by a hand lever, not shown. The wipers are so formed and arranged as to present a continuous inner acting edge shaped to embrace the heel portion of a shoe and to lay the upper inwardly over the vshoe bottom when they are advanced and closed. Each wiper, in Vaccordance with the illustrated embodiment of this invention, `has connected to it by a screw `8 an extension piece l0 which when in its operative position presents an inner acting edge in continuation of the acting the wiper extension edge of the main wiper plate. For securing this extension piece it is provided with a thin shank 12 and the wiper is formed with a pocket or recess extending forwardly from the screw 8 to receive the shank of the extension piece in a position in which the lower face of said shank and the lo-wer face of the plate are flush with each other. r1`he walls, and particularly the rear wall, of this pocket 0r recess forni abutments which assist the screw 8 in maintaining the extension rigid against the strains which the extension piece is called upon to withstand during its operation. The wiper plate has also a pocket or recess extending rearwardly from the screw 8 and shaped Yto receive the extension piece in an inoperative position. By loosening the screw without necessarily detaching it from the extension piece the latter can Vbe turned from its operativeto its inoperative position or vice versa' and then by tightening'the screw it may be held firmly in the position to'which has been adjusted. j

In a use of the invention which has been made with advantage the extension on that wiper' which is to'overwork the upper at the inner side of the shoe 'being lasted is shifted 'into its roperative position and is employed for wiping the upper into the deeply cut shank of such llasts as are largely in use at the present time. It is the custom to last a case of shoes for the right footY and thento make the necessary adjustments of the machine for lasting shoes for the other foot. vVith the described use of'this invention such adjustments .will include the loosening of the screw 8, swinging of the extension piece which has been in use into the rear pocket in its wiperplate, and tightening the screw to maintain the extension piece in place in that condition. The extension piece for the other wiper which is now to work at the inner side 0f the shoes is then moved to its operative position. Obviously the extension pieces for both wipers could be continued in operative posit-ion while working` on both right and left shoes if that were found convenient or both extension pieces could be rendered inoperative when their use is not desired. YThis invention furnishes wipers which in effect are of different lengths whereby a longer wiping edge is presented for action on one side of the shoe than on the other side. This is of importance inv lasting shoes on many stylesV of unsyminetrical lasts, one example Vof such lasts having been herein referred to and illustrated in the drawing.

Having explained the nature of this invention, I claim as new and desire to `secure by Letters Patent of the United States:

11. An end lasting mechanism comprising `end embracing wipers adapted for positioning movement to present for action at one side of the shoe a wiping edge which is substantially longer than the wiping edge presented for action at the other side of the shoe.

2. An end lasting mechanism having heel embracing wipers of which that one which acts at the inner side of the shoe extends farther forwardly toward or along the shank than does the wiper which acts at the outer side of the shoe.
